Patent SE-508506-C2 (SE)
Inventor: BOLIN THOMAL
IPC: H03F3/72
Filed: 1997-02-25
Abstract: The present invention relates to a power amplifier device (10), switchable for at least two separate basic frequency bands, for radio frequency signals with effective suppression of harmonics, where harmonics, corresponding to a first basic frequency band, can be permitted to overlap the frequency range of at least one second basic frequency band. The power amplifier device (10) comprises a power amplifier (1) and an impedance matching circuit (2), switchable by means of a PIN-diode, which provides a load impedance adapted to each individual basic frequency band. Furthermore, the power amplifier device comprises a filter device (3) comprising a fixed low-pass filter (3b) and a switchable filter (3b) acting as an engageable and disengageable notch filter, which comprises at least one reversible PIN-diode. This switchable filter (3a) allows to pass, in a first mode, signals in the first basic frequency band and suppresses at the same time at least one order of harmonics corresponding to this basic frequency band. In a second mode, the second basic frequency band is transmitted without appreciable losses, and harmonics are suppressed by the fixed low-pass filter (3a).

Abstract: A communication system (10), having dynamic nodes such as satellites (12), require narrow-tolerance communication parameters such as timing and frequency. A voice subscriber unit (26) establishes a traffic channel (17) by negotiating communication parameters. A user of voice subscriber unit (26) generates inherent voice pauses in communications. A data subscriber unit (31) possess a datagram for delivery through communication system (10). Instead of negotiating a dedicated traffic channel for delivery of the datagram, data subscriber unit (31) monitors an active voice subscriber unit (26) and determines if the communication parameters used by voice subscriber unit (26) are compatible for data subscriber unit (31). Data subscriber unit (31), upon detecting a voice pause by voice subscriber unit (26), transmits the datagram to satellite (12) using the negotiated communication parameters of voice subscriber unit (26).

Abstract: In a method for detecting a manipulation performed on digital information the erroneous determination of a manipulation during processing disturbances is prevented by subdividing the information into information subunits from each of which an identification is derived which is assigned to the respective information subunit. After processing the information subunits together with their identifications, potentially manipulated information subunits are determined on the basis of their identifications. This enables the whole of the information to be classified as manipulated if at least two information subunits which are correlated with respect to time or location have been determined to have been potentially manipulated.

Abstract: Изобретение касается способа стабилизации раствора или суспензии металлопротеазы для лучшего хранения и транспортировки такого фермента. N-блокированную аминокислоту добавляют к водному раствору или суспензии протеазы. Изобретение касается состава с металлопротеазой, стабилизированной с помощью N-блокированной аминокислоты. При добавлении N-бензилоксикарбониламинокислоты к металлопротеазе фермент стабилизирован даже в отсутствие избытка ионов Са. Соответственно обеспечивается хранение металлопротеазы в течение долгого времени, а транспортировка и хранение жидкого фермента соответственно упрощаются. Регенерация металлопротеазы улучшается в присутствии NPAA, когда указанный фермент используют в реакции связывания между N-блокированной аминокислотой и аминокислотным эфиром. Действие является наиболее заметным, когда N-бензилоксикарбониласпарагиновую кислоту используют в качестве N-бензилоксикарбониламинокислоты и фенилаланинметиловый эфир используют в качестве аминокислотного эфира в производстве аспартама.

Abstract: Изобретение относится к области диагностики состояния металла магистральных и промысловых трубопроводов. Повышение оперативности и надежности контроля металла трубопровода достигается за счет того, что устанавливают измерительную и регистрирующую аппаратуру, снабженную источником питания, в рабочее положение относительно трубопровода, возбуждают и принимают прошедшие через материал трубопровода импульсы ультразвуковых колебаний, первично обрабатывают и измеряют параметры последних, накапливают информацию об измеренных параметрах и впоследствии обрабатывают с помощью компьютера. Трубопровод разбивают на участки длиной 500-2000 м, на каждом из этих участков стационарно устанавливают со стороны наружной поверхности трубопровода измерительную и регистрирующую аппаратуру, снабженную источником питания. Осуществляют возбуждение импульсов с частотой колебаний ультразвукового диапазона 10 4 -10 6  Гц и прием импульсов ультразвуковых колебаний соответственно в начале и конце каждого из упомянутых участков. Принимают прямые, прошедшие через материал трубопровода импульсы. Для каждого из участков трубопровода производят первичную обработку принятых импульсов ультразвуковых колебаний, измерение их параметров и передачу информации для последующей обработки на компьютер, который устанавливают на мобильном контрольном центре. Передачу информации осуществляют непосредственно во время проведения контроля. Накопление в памяти компьютера переданной с каждого участка во время проведения каждого контроля информации осуществляют за весь период контроля. Подачу сигнала на включение и отключение измерительной и регистрирующей аппаратуры на каждом участке трубопровода осуществляют радиотехническими методами с вертолета или самолета. О состоянии качества материала трубопровода судят по результатам совместной обработки и сравнения информации об измеренных параметрах импульсов ультразвуковых колебаний в момент текущего контроля и накопленной в памяти компьютера информации об упомянутых параметрах за весь предыдущий период контроля. В качестве источника питания и коммуникационной сети связи с мобильным контрольным центром используют служебную телефонную линию, проложенную вдоль трубопровода. 3 з.п.ф-лы, 3 ил.
